China launches navigational satellite BeiDou-2The new Chinese navigational satellite BeiDou-2 launched Jan 16 at 16:12 UTC will use 1256.52-1280.52 MHz The Space Flight report says The Chinese have opened their 2010 campaign by orbiting a navigation satellite via a CZ-3C Chang Zheng-3C (CZ3C-3) launch vehicle from the Xi Chang satellite Launch Center, in Sichuan Province. Previously scheduled to take place last year, the launch of the new BeiDou-2 (Compass-G1) finally took place at 16:12 UTC on Saturday. The Compass constellation will consist of approximately 35 vehicles, including 30 MEO satellites, with nine satellites for each orbit plane and five GSO satellites. The satellites – developed from the DFH-3 satellite platform – will transmit signals on the following carrier frequencies: 1195.14-1219.14MHz, 1256.52-1280.52MHz, 1559.05-1563.15MHz and 1587.69-1591.79MHz. Some of the signals overlay the Galileo PRS band and the GPS M-code. The Compass Navigation Satellite System (CNSS) is China’s second-generation satellite navigation system, capable of providing continuous, real-time passive 3D geo-spatial positioning and speed measurement. The system will initially provide high-accuracy positioning services for users in China and its neighboring regions, covering an area of about 120 degrees longitude in the Northern Hemisphere. The long-term goal is to develop a global navigation satellite network similar to the GPS and GLONASS. Read the full Space Flight story at NasaSpaceFlight
